JACK FOR FENCE WIRE STRETCHERS Filed July 2, 1928 2 Sheets-Sheet 2 Patented Mar. 18, 1930 UNITE JAMES M. BUYER, OF URBANA, ILLINOIS JACK FOR FENCE-Winn s'rnE'roHEns Application filed July 2, 1928.

This invention relates to new and useful improvements in jacks for supporting fence wire stretchers and aims to provide a simple and inexpensive means whereby a conventional wire stretcher may be supported against a corner post for facilitating the stretching of the wire before its attachment to the corner post.

It is well known that it is a very diflicult matter to properly stretch wire before attaching the same to a corner post and my invention will overcome all of the disadvantages incident to the stretching of wire before its attachment to a corner post. i

In the drawings wherein like reference characters indicate corresponding parts throughout the several views Figure 1 is an elevation of a fence corner post at the opposite sides of which and in spaced relation thereto are brace posts, my

improved jack being illustrated in use.

Figure 2 is an elevation of the ack in folded position when not in use. 7

Figure 3 is an edge elevation thereof.

Figure 4 is a longitudinal section taken through the center of the ack plate.

Figure 5 is a longitudinal section taken through the plate at one end thereof.

Figure 6 is a fragmentary transverse section through the plate of the jack, and some of its associated elements, and

Figure 7 is a perspective of a tie rod pivotally connected with one end of the plate.

Now having particular reference to the drawings, my novel jack consists of a metal lic plate 5 of suitable size and shape. Pivoted adjacent one end of this plate and adjacent its opposite longitudinal edges are the inner ends of forwardly extending brace bars 66 the outer ends of which are pointed as at 7 for biting engagement into the corner fence post A as illustrated in Figure 1. Adjacent the inner edge of this plate 5 the same is formed with arcuate-shaped slots 8-8 within which are removable pins 99 carried by the brace bars 66 and serving to limit the swinging movement of the bars with respect to the plate. Adjacent the pointed ends of these bars the same are equipped with chains 10 59 10 adapted for engagement around the corner Serial No. 289,722.

post A the outer ends of these chains being provided with hooks 1111 whereby the chains may be secured in engagement around said posts. Pivoted to the outer end of the plate 5 intermediate the inner ends of the brace bars 66 is the inner right angular pin end of a tie rod 12 the pin of this rod designated13 being threaded for receiving nuts 1l1e at opposite sides of the plate so that the tie rod can be secured against swingingmovement or so that the same may be swung from the inoperative position as illustrated V in Figure 2 between the brace bars 66 to the operative position as illustrated in Figure 1, in which latter position the said tie rod is swung directly rearwardly with respect to the brace bars, and by reason of the rod 12 being equipped at its outer end with a chain length 15 said end may be secured to a brace post B in spaced relation with the corner post A. Adjacent the inner edge of the plate 5 intermediate the braceba'rs 66 is provided a hook or other suitable fastener 16 whereby to facilitate the attachment of any conventional type of wire stretcher C thereto, said wire stretcher being in turn attached to the strand of wire D being drawn toward the corner post A for stretching prior to its attachment to the corner post.

It will thus be seen that I have provided r a novel, simple and extremely useful jack for fence wire stretchers in order to facilitate the stretching of the wire at a corner post of the fence, and even though I have herein shown and-described the invention as consist- 5 ing of certain detail structural elements it is nevertheless to be understood that some changes may be made therein without affecting the spirit and scope of the appended claim.

Having thus described the invention, what I claim is r A jack for fence-wire stretchers, comprising a body plate having arcuate slots adjacent to one of its ends, said slots being also. adjacent to its side edges, means associated with said body plate for the attachment of a wire stretcher thereto, bars arranged alongside of and pivotally connected to the body plate adjacent to one end'thereof and prov jecting beyond the other end thereof and having pointed ends and also having adjacent said ends cables for the individual connection of said bars to a fence post, headed pins carried by said bars and disposed and movable in said arcuate slots of the body plate, and a tie rod pivotally connected to the body plate and adapted toextend therefromxin the direction opposite to that in which the said bars extend.

V In testimony whereof I aflix my signature.
